Hartford HealthCare (HHC) says it recently opened a $10.4 million cancer treatment center in Manchester.

The state's second largest health system on Tuesday said the three-story Hartford HealthCare Cancer Institute, located at 376 Tolland Turnpike, will provide multi-specialty care targeted at residents east of Hartford, which is home to its flagship facility, Hartford Hospital.

With its glass and brick exterior, the 37,581-square-foot cancer center can be seen from I-84 eastbound near exit 63.

"We know that bringing comprehensive cancer services into the community allows us to do a better job caring for our patients, so we have been working to bring the most advanced oncology care possible to a new location east of the river," said Dr. Peter Yu, the facility's medical director.

HHC provides cancer services at six hospitals in state and at other stand-alone locations, including in Plainville, Avon and Torrington.

The health system also plans to relocate one of its gynecologic oncology locations, currently in Glastonbury, to the new facility, according to an application submitted to the Connecticut Office of Health Strategy. So-called "GynOnc" services focus on cancers of the female reproductive system.

The health system expects most of its 500-plus patients in Glastonbury to transition to the new cancer center, it said.
